IMPROVEMENT IN PRESERVE-CANS.

Specification forming part of Letters Patent No. 20,485, dated June8,1858.

. To all whom, it may concern.-

Beit known that I, H. G. DAYTON, of Maysville, in the county of Masonand State of Kentucky, have invented a new and useful Improvement inPreserve-0ans; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, making part of this specification, in whichfiFigure l is a side View of a can with my improvement. Fig. 2 is acentral section of the same. Fig. 3 is a top view of the claspringemployed to confine the indiarubber band.

Similar letters of reference indicate corresponding parts in the severalfigures.

The nature of my invention consists in the employment of an india-rubberband in eom bination with a metal cover and an elastic metal clamp, theformer being attached permanently to the metal cover in such a manner asto enable it to lap over the sides of the can and cover the joint, andthe latter encircling the rubber band and serving, by its elasticity andthe shrinkage of the distended rubber band, to render the junctionbetween the body of the can and the cover perfectly air-tight. With thiscombination of metal cover, rubber band, and metal clasp very thin lightrubber can be used, and thus the covers can be made quite cheap comparedto what they can be when made entirely of heavy rubber, as in thepreserve-can of R. Davis.

To enable others to make and use my invention, I will proceed todescribe its construction and operation.

A is the can, made with its mouth of the full diameter of its body.

0 is the cover, made of tin-plate,witl1 a rim to fit over the mouth ofthe can.

B is the india-rubber band, made of a piece of tubing or a ring of sheetindia-rubber of a size in its normal condition much smaller than theexterior of the can, that it may require to be stretched to make it passonto the can, and hence made to hug the can very closely. One end ofthis band is attached securely and in an air-tight manner to the marginof the rim of the cover by turning up the said margin over it all round,as shown at a a, in Fig. 2. This band may be about three-quarters of aninch in width. Before the cover is applied to the can the band B isturned up over the top of it, as shown in red color in Fig. 2, and afterthe cover is put on the band is drawn down over the can, as shown inblack color in the same figure, and in which position it shrinks sotightly upon the can as to exclude perfectly all air from the jointbetween the can and cover.

D is a clasp-ring to secure the band B over the can, made of steel orother metal, either with or without a lock joint, as shown at b in Fig.3. If made of spring-steel and coiled, so as to form in its normalcondition a circle smaller than the can, no lock will be necessary, asthe ring will clasp the rubber tightly by its elasticity. This clasp isslipped on from the bottom of the can.

what I claimas my invention, and desire to secure by Letters Patent, is-

The employment of the rubber band in combination with a metal cover andmetal clamp,

substantially as and for the purposesset forth.
